Orient were losing 3-1 to Colchester before the fans took to the field.

Officials tried to calm fans and remove them off the pitch but their efforts failed.

Football League statement

“The decision to play the match to a conclusion was agreed with both managers and with the support of the match officials.

“The police and stadium security staff were happy for the match to restart and this took place at approximately 6.40pm.

“Despite requests for the fans to clear the pitch, there wasn’t sufficient movement to allow the game to restart following a pitch invasion.

“A decision was taken with the police to announce that the game had been abandoned, as it was felt this would help clear the pitch, which proved correct.

“However, it was deemed appropriate that the game needed to be played to a conclusion in order to maintain the integrity of the competition and in respect of Colchester United’s position of being able to qualify for the League Two play-offs.”
